Bifunctional Catalysis

Hydrocarbon hydrogenation also uses bifunctional catalysts. Ethylbenzene and 1-hexene were hydrogenated using clinoptilolite that had been swapped with Ni2+ and then decreased thermally. The hydrocracking of n-paraffin was evaluated in a natural erionite ore that had been calcined, exchanged with NH4+, and Ni2+. A catalyst life of more than a year is achievable, as shown by pilot plant runs. Bifunctional catalysts based on methanol synthesis component and synthetic zeolite may be thought of as a system with non-additive, synergistic features, regardless of the fabrication process. It is well known that the NBAC value, which describes the relative concentration of acidic centres in the bifunctional catalyst, determines the activity and selectivity of the bifunctional catalyst during the syngas conversion process. The acidic function of the bifunctional catalyst likewise expands when NBAC value rises, and the process of methanol conversion to DME and hydrocarbons is accelerated accordingly.
